Abstract: 1357258 Angular bending; straightening D L COLBATH 7 Sept 1972 [20 Sept 1970] 41610/72 Heading B3E A roll-forming machine comprises a frame 10 in which a path of movement for material to be formed is defined, an elongate rigid spine 120 removably supported on the frame, a plurality of forming members each secured to the spine at spaced points therealong, and means locating the spine so that the forming members are located along the path of movement. Spines having different sets of forming members can thus be readily interchanged. The frame in Fig. 2 consists of longitudinals 14 on feet 16, and includes a number of roll stands 24 in its upstream half, each stand including two pairs of rolls 42, 52, on driven shafts 44, 54, each roll pair being supported by bearings 46, 56 on a plate 62, 68. Plate 62 is fixedly mounted on longitudinals 14, but plate 68 is urged downwardly by springs 70 to accommodate materials of different thickness. Similar stands (26) in the downstream half of the machine have rolls of larger diameter set closer together. The stands 24, (26) have separate chain and sprocket drives from the same motor, and serve only to advance the material. The spine 120 is mounted on each upper plate 68 by brackets 122 having holes located on studs 126 on the plates, and is held down by latches 128 and bolts 130. On either side of the first stand 24, a guide, Fig. 4, hangs from the spine by bolts 138 in slots 140, so that the guide can be located laterally by adjustment of screws 142. Between subsequent stands 24, (26) are located roller-die stands such as 152, Fig. 7, which are hung from the spine and include plates 158 slotted at 160 and supporting rollers 166 which successively form lips B L  and flanges B F  on the material. The last stand does not form the profile of the material, but is vertically adjustable to prevent curvature of the work in a longitudinal vertical plane. In another embodiment, Fig. 11 (not shown), the spine supports rolls which both form and advance the work, being coupled to drives on the frame by releasable couplings and universal joints.

Title: Apparatus for the Consecutive or Selective Playback of Tapes containing Data Stored in a Number of Cassettes
IPC: G11B15/68
Filed: 1967-09-18
Abstract: 1,181,423. Feeding record tapes. STAAR S.A. 18 Sept., 1967 [15 June, 1967], No. 42393/67. Heading G5R. A plurality of tapes contained in cassettes 10 may be consecutively or selectively played back by apparatus 2 located below a horizontally movable bottomless magazine 6 divided into compartments 9 each of which may contain a cassette 10 standing on edge, horizontal movement of the magazine 6 being effective to bring each compartment in turn into alignment with vertical guides 170 so that the associated cassette may be released from the magazine 6 and descend, at first under gravity and subsequently under the action of elements which gradually become operative during the gravity-assisted descent, to an operative playback position in the apparatus 2. As shown, the magazine 6 moves in grooves 5 in a horizontal frame 3 while the cassettes 10 slide on rails 11 mounted on a base-plate 4. Withdrawal of a retaining rod (13) pivoted on the magazine 6 allows that cassette which is located above a slot 12 to fall into the guides 170, carrying with it in its descent first a slider 18 and then two tubes 178 in which are slidable two rods 177 secured to a movable plate 102 which, by virtue of parallel links 128, moves towards the cassette as it descends and inserts a capstan 112<SP>1</SP> and spindles 123, 194 into the cassette which comes to rest with the tape in engagement with a playback head 188, the cassette being latched in the operative position by a spring member 106. The sequence of operations is controlled by push-buttons (209, 210, 215), by gear-wheels (22 to 26) and cams driven by an electric motor 20, by a device which detects as described in Specification 1,122,041, the cessation of rotation of spindle 194 when all the tape has been wound off the supply reel of the operative cassette and initiates the raising of this cassette into the magazine and the stepping-on of the magazine to the next position under the control of a triangular latching member (91), and by a linkage (205) operated by the magazine 6 in its extreme position. If, due to misalignment, a descending cassette 10 is not penetrated by the drive mechanism carried by the moving plate 102, the operating cycle is modified so that the cassette is immediately raised into the magazine. This retraction of the operative cassette may be initiated also at any time by means of a push-button. In a modified construction (Figs. 31 and 32), the magazine is circular and rotatable, with the cassettes arranged radially and the retractable retaining rod (13) replaced by a slidable member (13<SP>1</SP>) disposed on the frame instead of on the magazine.

Fig. 3 shows a dry shaver in which the oscillators are mounted face to face on a fixed rail, their free ends being attached to a linearly reciprocatable rail 4<SP>1</SP> which drives the cutter block 24 through a pin 25. Each oscillator comprises a metal strip 1 sandwiched between a pair of ferro-electric ceramic strips 2 faced with metal electrodes 3 and the oscillators are attached to the rail 4 either by securing them in recesses by casting resin or casting them in the rail at the same time as it is moulded. In the shaver shown in Fig. 4, the oscillators are mounted side by side in the rail 4 and actuate a rotary oscillatory cutter block 44 by engaging at their free ends in a groove 443 in the block. The cutter block may be formed in a number of parts each driven by a group of oscillators, Fig. 7 (not shown). Alternatively, Fig. 5, a single rotary cutter block 44 may be actuated by a plurality of oscillators which are fixed at both ends in a frame 471, their centres where the anti-nodes occur being connected together by a comb-shaped web 48 having a projection 481 for driving the cutter block. Fig. 8(a) shows a further embodiment wherein a pair of cutting heads 74 1 , 74 2  are linearly reciprocated in opposite directions by hinged or resilient bars 71 1 , 71 2  which are moved towards and away from each other by rails 4 1 , 4 2  between which bending oscillators 76 are mounted. The oscillators may all bend in the same direction or groups thereof may bend in opposite directions to reduce out-of-balance forces. One of the cutting heads in this arrangement may be replaced by the outer cutting foil and the arrangement may be adapted to actuate a single cutting head by omitting one of the bars 71 1  or 71 2  and fixing the adjacent rail 4 1  or 4 2  to the housing 7, Fig. 8(d) (not shown). The shaver shown in Fig. 3 may have two cutter blocks each operated by a group of oscillators, the two groups being mounted on the rail 4, Fig. 6 (not shown). Alternatively the two groups may actuate a single cutter block, one group oscillating in opposition to the other group and being connected thereto by a two armed lever, Fig. 9 (not shown).
